Improves cold flow of fuel

HMS Winter Diesel Treatment Fuel Enhancer is a premium diesel-fuel enhancer designed to lower the fuel-operability temperature limit and the fuel pour point while raising the cetane.  It improves fuel lubricity without adding sulfur, increases fuel combustibility, and cleans the entire fuel system. This improves horsepower and torque output and increases fuel and engine efficiency, resulting in increased fuel economy and reduced fuel-related maintenance costs and downtime.

HMS Winter Diesel Treatment is used in all types and sizes of diesel engines such as trucks, trains, ships, generators, compressors, tractors, passenger cars, and road-building and mining machinery.  It micro-emulsifies water, helping to protect the fuel system from the negative effects of moisture and contains an algaecide and an anti-coagulant.

HMS Winter Diesel Treatment also helps prevent diesel fuel from gelling in colder weather.

HMS Winter Diesel Treatment removes harmful carbon from the engine’s upper cylinders and prevents future buildup. The atomizing capabilities improve combustion by causing the fuel to burn uniformly, and its powerful detergents help keep the tank, injectors, pumps and fuel lines clean.

HMS Winter Diesel Treatment contains concentrated HMS Engine Treatment to replace the lubricity lost with ultra-low-sulfur diesel fuel. In addition to treating and protecting the fuel pumps and injectors, HMS Winter Diesel Treatment also protects combustion-chamber components for a more efficient and trouble-free operation. It is non-corrosive and will not harm any component of the fuel system.
